As a precursor to the modern dishwasher, in 1850, Joel Houghton patented a machine that splashed waters on dishes. Not satisfied by the largely ineffective device, Jospehine Cochran set out to invent the dishwasher herself. In 1886, she created a hand operated, mechanical machine that sprayed warm, soapy water by using a hand crank. She unveiled this new invention at the 1893 World’s Fair; however, only hotels and restaurants purchased her dishwasher. The general public did not have dishwashers widely until the 1950s.
